Finally, after several years of foot dragging, Im migrating to a PC from a Mac for a myriad of reasons, none of which are the focus of this thread. Ive installed Poser 4 with both upgrades recommended by CL, and Ive dragged over an inordinately large Runtime folder (50 gigs) into the Poser 4 folder. The files within have all been translated to PC format using Mac Converter. I can open each folder and see the files with. So far, so good. Now when I open Poser on the PC, the library categories show up, but within those categories, nothing appears. For example, under charactersanimals, none of the animal characters appear in Poser. On the desktop, however, theyre showing up as text files WITH the .cr2 extension visible: For example, I have Tiger (the rsr file) and(Tiger.cr2 in the Animals folder. Anyone have any ideas on whats causing this, and if so, what the fix is?
